1200cm

20x50= 1000x1/2x2= 1000
10x20=200x2x1/2=200
1000+200=1200
the area of the kite is 1200 cm

Select all of the potential solution(s) of the equation 2log5x = log54.

Vanyuwa [196]

Answer:

x = ±2

Step-by-step explanation:

A equation is given to us , which is ,

$\longrightarrow 2log_5(x) = log_5 4$

From properties of logarithm we know that ,

$\longrightarrow alog\ m = log \ m^a$

Applying this to LHS , we have ;

$\longrightarrow log_5 x^2 = log_5 4$

Now the bases of logarithm on LHS and RHS is same . On comparing , we have ;

$\longrightarrow x^2 = 4$

Put square root on both sides,

$\longrightarrow x =\sqrt{4}$

Simplify ,

$\longrightarrow \underline{\underline{ x =\pm 2 }}$

This is the required answer.

If x^2 - 6xy = z - 9y^2, make x the subject of the formula

alukav5142 [94]

$~~~~x^2-6xy=z-9y^2\\\\\implies x^2- 2\cdot x\cdot 3y + (3y)^2 - (3y)^2 = z-9y^2\\ \\\implies (x-3y)^2 -9y^2 = z-9y^2\\\\\implies (x-3y)^2 = z\\\\\implies x - 3y =\pm\sqrt z\\\\\implies x = 3y\pm\sqrt z$

The parking lot for a hotel should have 114 parking spaces. If ech row can have 13 parking spaces, then the minimum nukber of ro

MArishka [77]

So @mathmate deleted my comment because "I wasn't explaining my answer" well I did

I clearly stated that you have to make educated guess and I showed how I GOT my answer

so i guess here is my "proper" answer

There is no specific formula for this, so you can make an educated guess

for example:

13*5 = 65 (this isn't right because we need a minimum of 114)

so we continue the guessing

I then next tried

13*9

I got 117,

117 is more than 113

making 9 the minimum amount of rows for the hotel parking lot

there ya go @mathmate is that clear enough?

Alexa knock down 70 bowling pins in 10 frames. in each frame, alexa nocked down the same number of pins. how many pins did Alexa

hichkok12 [17]

The answer would be 7 because you would divide 70 by 10 to find out how many were per frame.
